         2 . The noise reduction device according to  claim 1 , wherein the second end of the tubular body is flat. 
     
     
         3 . The noise reduction device according to  claim 1 , wherein the at least one opening in the second end of the tubular body has a diameter that is at least 50% smaller than the diameter of the opening in the first end. 
     
     
         4 . The noise reduction device according to  claim 1 , wherein the at least one opening in the second end of the tubular body has parallel sidewalls. 
     
     
         5 . The noise reduction device according to  claim 1 , wherein the at least one opening in the second end of the tubular body has flared walls. 
     
     
         6 . The noise reduction device according to  claim 1 , wherein the second end of the tubular body has a plurality of openings. 
     
     
         7 . A compressor assembly comprising:
 a compressor having a head portion mounted thereto, a discharge port in the head portion and a discharge tube connected to the discharge port in the head portion;   a storage tank having an intake port connected to the discharge tube to receive pressurized fluid from the compressor;   a check valve arranged between the compressor and the storage tank; and   a muffler disposed between the compressor and an inner wall of the storage tank, the muffler comprising a tubular body having an opening in a first end, a second end opposite the first end, and cavity located between the first end and the second end, the second end having at least one opening with a diameter smaller than the diameter of the opening in the first end.   
     
     
         8 . The noise reduction assembly according to  claim 7 , wherein the muffler is disposed within the head portion of the compressor. 
     
     
         9 . The noise reduction assembly according to  claim 7 , wherein the muffler is disposed within the discharge tube. 
     
     
         10 . The noise reduction assembly according to  claim 7 , wherein the muffler is disposed between the compressor head and the check valve. 
     
     
         11 . The noise reduction assembly according to  claim 10 , wherein the muffler is disposed between the discharge tube and the check valve. 
     
     
         12 . The noise reduction assembly according to  claim 7 , wherein the intake port of the storage tank is outside of a condensate line. 
     
     
         13 . The noise reduction assembly according to  claim 7 , wherein the muffler is disposed within the storage tank and the opening in a first end circumscribes and is crimped to the fluid outlet portion of the check valve. 
     
     
         14 . A method of making a noise reduction assembly in an air compressor, the method comprising:
 providing an air compressor operatively connectable to an air storage tank by a discharge tube, the discharge tube having a receiving end for receiving compressed air from the compressor and a discharge end for discharging the compressed air into an intake port in the air storage tank; and   welding a noise reduction device to the intake port in the air storage tank, the noise reduction device including:
 a tubular body having an open first end, a second end opposite the first end, and a cavity located between the first end and the second end, the second end being opposite the first end and having at least one opening, the at least one opening having a diameter smaller than the diameter of the opening in the first end; 
 wherein the at least one opening in the second end is adjacent to a point directly opposite from the opening in the first end.
